The VOCALLUX VR-C29 Digital Portable Receiver uses the UHF band. By adopting Digital Modulation (QPSK) technique, it can be used many channels in the same place without interference. |
A true digital wireless microphone system in the 900MHz
UHF band, VOCALLUX
can solve common multi-channel problems such as
interference, the appearance of unspecified radio waves,
and incidences of white noise while using analog wireless
microphones.
Most digital wireless microphones are ISM Band 2.4GHz.
However, this band has a poor radio environment because many devices such as
Wi-Fi and Bluetooth are used together. VOCALLUX is Korea first 925~937.5MHz
band dedicated wireless microphone system than adopts the digital modulation
technique.
The IDR-A19 receiver uses the QPSK modulation technique
to resist noises such as phase noise and has immunity to multipath fading
distortion and noise. The result is more than three times higher frequency
efficiency (multi-channel) than conventional analog modulation technique (FM).
In addition, high dynamic range, high-quality 48kHz / 24
Bit signal sampling, and the appropriate audio codec algorithm according to
domestic radio regulation laws are applied in the process of encoding, which
enables the product to maintain high reliability and security.
If used as a rack-type in the half-rack
size, the product can be connected using the enclosed special
bracket(IDB-001/002)
If two IDR-A19s
are connected at the same time, 2 units can be connected in 1U using the
provided IDB-003 dedicated bracket.
The LCD panel on
the front of the receiver makes it easy to visually check the frequency used
and the audio gain.
The frequency can
be changed through groups and channels, and the information can be conveniently
matched to the corresponding transmitter.
The frequency can
be tuned via the "SYNC" button and IR port.
≫ Applications
Ideal for
multi-channel applications needed in large auditoriums, small auditoriums, and
training centers. According to the characteristics of the cartridge.
